Certification

1. Japan power supply product certification

Japanese power supply product certification has PSE certification. All electrical and electronic products sold in the Japanese market must pass PSE certification. This certification requires that the product must comply with a series of Japanese electrical safety, EMC and green standards to ensure that the product is safe, reliable, and environmentally friendly standards.

2. European power supply product certification

European power supply product certification has CE certification. CE certification is a product certification required by the European Union, if the product is sold in the European market, it must pass CE certification. This certification requires that the product must comply with a series of technical standards and regulations required by the European Union to ensure that the product is legal, safe and reliable in the European market.

Basic functions of DC regulated power supply

DC regulated power supply generally has multiple outputs: for example, it provides a fixed output of 5V and 2A; Provide two channels (A and b) with adjustable output of 0 ~ 24V and 0 ~ 1a. The adjustable output generally has two working modes: voltage stabilization and current stabilization. These two working modes are automatically converted with the change of load, and the LED on the front panel of the instrument displays the CV and CC modes. Generally, the green light indicates CV (voltage stabilization) and the red light indicates CC (current stabilization). Some regulated power supplies also provide a-way and b-way series work and master-slave tracking work mode at the same time. If circuit a is the main circuit and circuit B is the slave circuit, when tracking the working mode, the output voltage of the slave circuit changes with the main circuit, which is more suitable for occasions requiring symmetrical bipolar power supply. If two circuits a and B work in series, they can output 0 ~ 48V and 0 ~ 1A DC power supply; In series tracking mode, it can output 0 ~ ± 24V and 0 ~ 1A DC power supply.
